Abstract

PURPOSE: To make a power source inexpensive by enabling a motor for turning a flywheel, to perform energy accumulating operation for accumulating energy for a medium lever serving as a driving source operating a mechincal operation part.
CONSTITUTION: Since the toothless part of partially-toothed wheel 52 is less than half the entire curcumference of the wheel, convex part 54 comes in contact with the 3rd lever part 48 at a position farther away from support shaft 44 when medium lever 43 is turned from a cassette ejection state to a play state as shown in the figure, wherefore the needed turning force of partially-toothed wheel 52 is relatively small while medium lever spring 49 can effectively be accumulated with energy. The electromagnetic holding method of holding selectively medium level 43 turning against the elasticity of medium level spring 49 uses the linkage among the 3rd lever part 48, convex part 54, partially-toothed wheel 52, locked part 55, and lock member 57, and electromagnet 59 which holds lock member 57 turning against the elasticity of spring 58.
